Blue Wildindigo (Baptisia australis var. minor)
Blue Wildindigo Baptisia australis (L.) R. Br. var. minor (Lehn.) Fern. (PEA FAMILY)
Blue wildindigo is an erect, solitary perennial 1 1/2-3 ft tall, glabrous throughout. The leaves are palmately trifoliolate with oblong leaflets and moderate lanceolate stipules. The inflorescence is an erect, terminal raceme with large blue pea flowers. The legume is 1-3 in. long, ellipsoid, with a beaked tip. The pods turn purplish-black at maturity. The pods rattle profusely when mature, due to the loose seeds inside, but seeds are seldom found in the pods since insect predation is almost universal.
